For those who dealt with November’s wild weather, you know the month was cold, wet and unseasonably snowy.

As we end the month with a chance of light rain - or snow - figures from the Northeast Regional Climate Center show a month of extremes.

Let’s take a look back and a peek at what’s in store for next month.

The rain

Rainfall totals were nearly double across the state, averaging about 3 inches above the normal 3.76 inches for the month. On 14 of 29 days in November, there was there was measurable precipitation.

The cold

The warmest day of the month was on Nov. 1 when the temperature hit a toasty 70 degrees in Danbury.

After that, we began a month-long slide into winterlike weather.

Temperatures averages were well below normal. Hartford average temperature of 38.8 degrees was 3.8 inches below average; Danbury’s 39 degrees, 2 below normal; Sikorsky Memorial Airport in Stratford was 1.8 degrees below average and Tweed-New Haven, 0.7 degrees colder than normal.

The day after Thanksgiving - Black Friday - was the coldest day of the month with a low of 5 degrees in Hartford, 6 in Danbury and 13 in Stratford and New Haven.

The snow

The biggest surprise of the month was a Nov. 15 snowstorm that brought 10.9 inches in New Fairfield, 8.2 in Newtown, 7.9 in Danbury and between 4 and 6 inches along the Long Island Sound shoreline.

The snow arrived at the worst time - just before the PM commute. In total, State Police responded to 1,341 snow-related calls for service, two of which were accidents with serious injuries. Of those calls, 230 were for accidents, ten of which involved minor injuries.

In Stamford, at peak rush hour, around 5:15 p.m., the Merritt Parkway north was closed between Exits 35 and 36 because of, “many motor vehicle accidents and disabled vehicles,” according to the state Department of Transportation. That closure was still in effect more than an hour later.

What’s next?

A weak upper level disturbance will move over the area Friday bringing a chance for light precipitation this afternoon and evening.

The precipitation may be predominately light snow or a mix with light rain across the interior of southern Connecticut.

Precipitation amounts are light and no snow accumulation is expected. Elsewhere, any precipitation will be in the form of light rain. Temperatures will be below normal for this time of year, with highs in the upper 30 to lower 40s.

High pressure returns tonight into Saturday morning and then moves offshore Saturday afternoon. A warm front will gradually approach from the south Saturday night bringing widespread rain. The rain will taper off Sunday morning.

Temperatures on Saturday will remain chilly in the 40s, but then warm significantly on Sunday as the warm front moves north of the area. Highs on Sunday are forecast to reach the middle and upper 50s with some lower 60s possible in the New York City metro area.

Cold December in the forecast

A colder air mass moves in with a re-enforcing cold front during on Monday. The colder air will remain in place through the week.

The Climate Prediction Center has the Northeast with the coldest temperatures in the U.S. from Dec. 7-13 with up to a 70 percent probability temperatures will be 70 percent below normal.

There’s an even chance of above or below normal precipitation during that period.

All of this is good news for ski resorts that have a strong start to the season.
